Abstract

"Green environmental practices are increasingly important in combating serious global energy and environmental issues. Most wastewater treatment facilities were built when energy costs were not a concern; however, an increasing demand for energy, changing climatic conditions, and constrained energy supplies have resulted in the need to apply more energy-conscious choices in the maintenance or upgrade of existing wastewater treatment facilities. A detailed analysis of the majority of water and wastewater treatment services shows that most facilities operate far below the efficiency levels needed for effective energy use. Failure to comply with regulated environmental standards is also a problem. Although standards exist for both energy and environmental management systems, no integrated process has been developed to address the concerns of communities wishing to lessen their environmental impact while also reducing energy utilization rates. The current research has developed an integrated model that combines both energy and environmental management systems models. It offers a holistic view of both approaches, maps linkages, and suggests an integrated process design capable of meeting high-performing energy management and environmental standards. The model presented here has been validated by a case study on the Rolla Southeast Wastewater Treatment Plant. Data on plant performance was collected, studied, and analyzed and the results provide the basis for suggestions to improve operational techniques. The significant factors contributing to both energy and environmental systems are identified and balanced with considerations of cost"--Abstract, page iii.
